LITTLE ROCK (AP) — U.S. Rep. Tom Cotton’s campaign says he’s raised $611,341 over the past three months as he prepares for a re-election bid or a potential Senate run.

Cotton’s campaign said the freshman Republican congressman from Arkansas has $1.04 million cash on hand. Cotton represents the 4th Congressional District in south and west Arkansas, and was first elected last year.

Cotton, of Dardanelle, is viewed as a potential challenger to Democratic U.S. Sen. Mark Pryor next year. He’s already been targeted by Democratic groups that have run ads criticizing the Republican lawmaker.

Cotton has indicated he’ll make a decision about his political future later this year.
